We are all familiar with cultivation novels, but most narratives primarily revolve around human cultivators. Progenitor of Myriad Demons introduces a refreshing and unique angle: demon cultivation. The protagonist, De Thich Thien, was once a brilliant individual from the modern world, the eldest son of an affluent family, and a prodigy who effortlessly mastered every endeavor. However, his promising life was cut short by the betrayal of his own kin. He subsequently transmigrated into a cultivation realm, reincarnating as a vulnerable tiger cub. From this unexpected new beginning, De Thich Thien embarks on an arduous and perilous journey, cultivating his demonic powers to ascend to the peak of strength and unravel the ultimate mysteries of the universe.
